Subject: [PATCH] Block Enderpearl Travel Exploit
|
|
|
|
Players are able to use alt accounts and enderpearls to travel
|
|
long distances utilizing the pearls in unloaded chunks and loading
|
|
the chunk later when convenient.
|
|
|
|
This disables that by not saving the thrower when the chunk is unloaded.
|
|
|
|
This is mainly useful for survival servers that do not allow freeform teleporting.
